Total revenue for 2012 was approximately $42.8 million compared to approximately $62.1 million for the same period in 2011. The decrease in total revenue was the result of the Company's largest customer's decision to modify its timelines for installation in the field.

Gross margins for the year ended December 31, 2012, were 42.7% compared to 43.2% for the same period in 2011. The Company attributed the stability of its gross margins to the commercial scale of production and deployment achieved over the past two years.

"During fiscal 2012, we continued to make a number of strategic investments to support our long-term growth. In particular, there are three that will be crucial to our success in the coming years. In working with our marquee customer, we further demonstrated the scalability and robustness of our technology platform," commented President and Chief Executive Officer, John J. Joyce.

Continued Mr. Joyce, "We successfully broadened our product and application portfolios with the introduction of the Ambient MicroNode, Ambient MiniNode, and our AmbientPQM (power quality monitoring) application. Each of these additions provides customers with added flexibility and capability suited to a utility's unique requirements. And, we continued to strategically invest resources in our sales and marketing teams. We are encouraged by the market's initial interest and acceptance of these enhancements."
Research and development expenses were approximately $14.3 million for year ended December 31, 2012, compared to approximately $11.7 million for the same period in 2011. The increase in research and development was due primarily to increased personnel and consultant expenses required for the continued development of the Company's communications nodes, enhancements of the AmbientNMS®, and other product development efforts.

Selling, general, and administrative expenses for year ended December 31, 2012, were approximately $9.6 million compared to $8.2 million for the same period in 2011. The increase in selling, general, and administrative expenses was due to an increase in personnel and related costs, and increased efforts to market and commercialize the Company's communications platform.

Net loss for the year ended December 31, 2012, was approximately $5.4 million, or $0.33 per share, compared to net income of approximately $10.1 million, or $0.59 per diluted share, for the same period in 2011. Non-cash expenses included in net loss totaled approximately $3.5 million during the year ended December 31, 2012, consisting of depreciation expense, stock-based compensation expense, and the write-off of deferred finance costs.

Cash and cash equivalents totaled $13.3 million as of December 31, 2012, compared to $18.0 million at December 31, 2011. Total working capital was $12.1 million as of December 31, 2012, compared to $14.3 million at December 31, 2011.
